中文摘要：

针对传统二进制相移键控调制信号在水声信道下需要较长的同步符号持续时间的问题,提出了基于二进制偏移载波调制信号的新型水声同步方案.对BOC信号的原理进行了讨论,通过理论推导和仿真分析,比较了提出的方案和传统方法.

英文摘要：

Aiming at the long synchronization symbol durance time of conventional BPSK modulated signal, the underwater acoustic （UWA） synchronization scheme based on BOC modulated signal is introduced. The principles of BOC signal is discussed, and the comparison of theory deduction and numerical results have been achieved between the proposed and conventional methods.
